Painting outside of house

[Ruth541]

Th window sills on the outside of my house are made of stone and the paint on them is pealing and rather grubby looking. I want to clean this off/smooth it over so that I can give it a fresh coat of paint. Any suggestions how best to get the old paint off?

Use a wire brush - the wire bristles will soon get it off.

And repaint with a good masonry paint.

Wire brush and some sandpaper.
Depends if its been painted with masonry paint , sounds like it may have been glossw ?
Either way you can undercoat the sills then paint with either gloss or masonry paint.
The choice is yours.

I've just done mine !
Use a paint stripping tool to get the 'big bits' off..........I then peeled the paint off to an acceptable point, i.e. joint in stonework, change of direction, etc. Then a good stiff wire brush to take care of the flaky bits.
I repainted them using a 'Pliolite' brilliant white paint. This is an oil-based masonry paint and in addition to covering very well and looking very smart, any future dirt can just be blasted off with a pressure washer as it will 'sit' on the surface instead of permeating through....................or at least that's what I was told :o)
